a516 grade 70 container steel for engineering and machine structural use

Beijing machining center has more than 1000 employees, including 360 technicians, 28 engineers, 6 senior welders, 15 professional welders, 52 bachelor's degree, 3 doctor's degree, and 8 R & D team. It is a professional a516 grade 70 container steel production team combining theory and practice. With an annual output of 80000 tons, looking forward to the future, our company continues to strengthen the advantages of a516 grade 70 container steel leading suppliers in the four steel fields of steel plate, steel pipe, stainless steel and special steel.

It is not the thicker the steel plate is, the better. The larger steel plate thickness means higher price and purchase cost, and it is also not inconvenient for transportation. Besides, the thickness of a516 grade 70 container steel, steel plate has relation to the safety, so the thickness of steel plate is not determined at random, and the size data of steel plate should be strictly planned according to the requirements of drawings. Therefore, it is necessary to select the appropriate steel plate material and specification according to the use.

Compared with ordinary steel, the a516 grade 70 container steel special steel has the following characteristics. First, the special steel has better physical properties, higher strength, stronger compressive strength, and better precision. Second, the special steel has better chemical properties, such as high temperature resistance, low temperature resistance and corrosion resistance. Third, the composition of the special steel is more diversified, which can be synthesized by integrating other elements, such as alloy steel, high carbon steel, etc. Fourth, special steel is more flexible for processing.

The final heat treatment of quenched and tempered alloy steel, a516 grade 70 container steel is quenching and high temperature tempering. The hardenability of quenched and tempered alloy steel is high, and oil is generally used. When the hardenability is very high, it can even be air cooled, which can reduce the defects of heat treatment. The final properties of quenched and tempered alloy steel depend on tempering temperature. Generally, it is tempered at 500 ℃ - 650 ℃. The required properties can be obtained by selecting tempering temperature. In order to prevent the second kind of temper brittleness, fast cooling (water cooling or oil cooling) after tempering is beneficial to the improvement of toughness.

Delivery status: 16MnDR steel plate is normalized or normalized and tempered. 6-60mm16MnDR-40℃ impact, 60-120mm16MnDR-30℃ impact.
Ultrasonic testing of 16MnDR steel plates: The a516 grade 70 container steel plates delivered in the normalized or normalized and tempered state with thickness greater than 20mm and the steel plates delivered in the quenched and tempered state with thickness greater than 16mm shall be ultrasonically tested one by one.
